To all whom itmay concern:

Be it known'that I, JOHN B. FOLEY, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a certain new and useful Improvement in SashLooks or Holders, and do hereby declare that the following is afull,-clear, and exact descrip tion thereof.

Reference being had to the accompanying drawings, Figure 1 is aperspective view of a car window lock embodying my invention; Fig. 2 afront elevation thereof, the bolt being shown as withdrawn in dottedlines; and

; Fig. 3 a horizontal section on. the line 33 of Fig. 1.

My invention relates to sash locks or holders, and more particularly toa lock adapted for use on the windows of railroad cars, and the objectof my invention is to provide a lock of such construction that the samelook is applicable to either the right or the left side of the Window;one whose construction will be simpler and more compact than the looknow in use; and that will be more convenient of manipulation than thelock in common use; and to this end my invention consists in the lock orholder constructed substantially as hereinafter specified and claimed.

As is well known, the form of lock used on railroad car windows has anoperating lever for retracting the sliding bolt, and considerablemovement of the handle end of the lever is necessary to secure anadequate throw of the bolt. Any undue movement of the hand in operatingthe lock is not only objectionable on its own account, but the greaterthe movement of the lever, and as well the arrangement of the parts dueto the employment of the lever, add to the bulk of the device as awhole. Moreover, with the lever type of look now in use, it is necessaryto make the looks right and left, so that a double stock must be carriedby the dealer to suit the requirements according to the side of thewindow on which the lock is to be used.

In constructing a lock to embody my invention, I employ a casing orhousing in the form of an oblong chambered block, having on its upperand lower sides perforated ears 11 for screws for securing the casing tothe sash, the casing being provided with holes or perforations in itsopposite ends in which are slidably mounted a horizontal bolt 12.Fastened directly and rigidly to the bolt within the casing is anoperating handle or finger piece 13, having ashank that passes through aslot in, the outer front wall-of-the casing, and outside ofthe-latterhas aside surface that-is shaped or formed with such curvature as to beadapted for. the convene ient. application toit of the forefingerapplied to the side thereofnext the window"frame,-so

that by lateral or side-wise pressure away from the latter, the bolt maybe moved to disengage it from the locking hole, notch or keeper of thewindow frame. The bolt is moved to and yieldingly held in lookingposition by means of a coil spring 14 that encircles the bolt and hasone end engaging a shoulder or enlargement 15 thereon, and its other endengaging the inner surface of one of the end walls of the casing.

Projecting horizontally outward from the front Wall of the casing, is alug or ear 16, that constitutes a supporting surface for the thumb whenthe bolt is to be retracted by the application of the forefinger to thehandle 13, and said thumb piece is so positioned that the bolt handle ismoved toward it by the action of the forefinger thereon, and the side ofthe handle towards the thumb piece is recessed to provide at its top andbottom overhanging lips or flanges 17 to respectively engage the upperand lower sides of the thumb piece when the bolt is fully retracted, sothat when the sash is to be raised or lifted, the strain or pressurewill not fall upon the bolt, but will be applied to the thumb piece bythe engagement of the lower lip or flange of the handle with the thumbpiece, and thus the strain resulting from the lifting of the sash willbe borne by the casing. I provide the bolt handle with the lip or flangeat both top and bottom in order to provide an engaging surface betweenthe handle and the thumb piece for lifting the sash whether the bolt isat the right or the left side of the window, and it will be a parentthat by reason of the projection of the bolt handle and the thumb piece,at the front or outer side of the lock, the same look is applicablewithout any adjustment or change to either side of the window, whereaswith the lever type of lock to which I have referred, where the operatinend of the lever protrudes at the side of t e lock, it is impossible touse the same look indifferently at either side of the window.

The ap lication of power to move the bolt by a han le directly connectedto and forming a part of the bolt, instead of through the medium of alever, not only affords the valuable advantage of applicability of thesame look to either side of the Window without adjustment or change, butthe amount of movement of the finger in operating the bolt need be nogreater than the amount of movement necessary to disengage the bolt,whereas with the lever the amount of movement of the finger is greaterthan the extent of movement of the bolt, and I produce a simplerconstruction, am enabled to use a better form of operating spring, thedevice as a whole is much more compact, and the finger and thumbengaging parts are situated so that they can be more easily andcomfortably caught hold of, and power applied to raise the sash moreadvantageously than is eases? I o the case with the lever type of lockgenerally used. 20

What I claim is In a sash lock or holder, the combination of a casing, ahorizontally sliding bolt, a handle fixedly attached to and projectingfrom the bolt for engagement by the finger, 25 and a lug or earprojecting from the casing adapted for engagement by the thumb, thehandle having a lug-engaging lip or flange, situated to engage an undersurface of the lug.

In testimony whereof, I afiix my signature 3f) in presence of twowitnesses.
